Application filed March 29, 1824, Serial No. 702317;. Renewed March 5, 1928.

This invention relates to envelopes, and

has for its primary object, the provision ofan envelope which can be used a number of times, being provided with means whereby the envelope can be addressed for these different uses, and the parts arranged so that only one address will appear at a time,

the previous addresses being concealed from view.

The nature and advantages of-the invention .will be better understood when the following detaileddescription is read. in con nection with the accompanying drawings, the invention residing in the construction, combination, and arrangement of parts as claimed.

In the drawings forming part of this application, like numerals of reference indi-. cate similar parts 1n the several views, andwherein z- 1 Figure 1 is a front elevation of an envelope constructed in accordance with the present invention.

Figure 2 is a sectional view taken on the line 2-2 of Figure 1.

Figure 3is a view similar to Figure 1 of a modified form of the invention.

Figure 4 is a fragmentary rear elevation.

Figure 5 is a view in elevation of an envelope with the front wall partly broken away showing the arrangement of the tongues.

Figure 6 is a plan view of the blank from which the envelope is constructed.

Referring to the drawings in detail, 10 indicates an envelope which possesses the same general outline or configuration of any well known envelope, including a closure flap 11, which can be secured to the rear wall 12 of the envelope by a fastener 13 of any well known construction. This permits the envelope to be opened and closed when desired without tearing or otherwise injuring the envelope. If desired, use may be made of a seal 13' to prevent the envelope from being opened by an unauthorized person Without giving indication of the fact that the envelope has been opened, and the arrangement of this seal is clearly illustrated in Figure 4. The seal consists of a v.

rectangular piece of any suitable material having a transverse line ofperforations 14' which when theseal is placed upon the envelope is adapted to be arranged in al1gnment with the lower edge of the flap 11. In

accordance with the present invention, the

front of the envelope provided with an elongatedslot 15 through which the addresses 'can. be readily observed, and if deenvelop'e.

Arranged within the envelope and rising from the upper edge thereof is a'plurality of tongues 17, upon which the address or.

addressesare adapted to be written. By reason of this construction, the envelope can be used any number of times, this depending of courseupon the number .of tongues with which the envelope is provided. It is' to be understood that-the envelope jean-vary in size and configuration without departing parentstrip 17 to protect the contents of the from the spiritof the invention, and that the envelope can be constructed in any manner whatsoever in order to produce'the con structionillustrated. Whenthe contents are of whatever other tongue is used for the address. p

In Figure 3, I, have illustrated a modified form of my invention which varies from the form just described in that the front wall 18 of the envelope is provided with a plurality of windows or openings 19 in contra-distinction to the elongated above referred to. In this form of the, invention there is a tongue 20 provided for each'window orbpening 19, and the enslot,

velope isused in the same manner as described in connection'with the preferred form' of the lnvention; I window or opening 19 can be covered from one side by a strip of transparent material 21 to protect the contents of the envelope.

As above stated, the envelope may be'constructed in any. suitable manner in order to provide the same with the essential features of the invention, but I preferably construct the envelope from a single blank of material illustrated in Figure '6.v As shown in this figureythe blank is divided by fold lines 22 into three sections indicated at 23, 241, and 25 r If desired, each respectively, in addition to including a closure flap 26. The section 23 constitutes the front Wall of the envelope which is provided with the windows or openings 27, while the section 25 constitutesthe rear wall of the envelope, The section 24 which is arranged intermediate the sections 23 and 25 is cut as at 29 to provide a plurality of separable sections which are folded to provide a tongue which is arranged between the front and rear walls of the envelope in the same relation to thewindows 27 as theitongues described above. When the separated portions are folded as above stated to provide these tongues, the section 24: is folded upon the section 23 between the latter and the section 25, after which the side flaps 31 are folded toward each other and effectively secured to the outer side of the side of the section 25. The closure flap 26 is adapted to be secured to the rear wall of the envelope by a snap fastener 33 of any suitable construction. In any form of the invention, the front wall of the envelope is provided with an opening 33 in the upper right hand corner thereof,

7 which opening is slightly larger than the size of the postage stamp to be secured to the enclosed matter so that the envelope can be reused, Without the presence of the cancelled postage stamp. It will be further noted that the envelope can'be used any number of times, and to as many addresses as there are names on the tongues.

WVhile .it is believed that from the fore-, going description, the nature and advantages of the invention will be readily apparent, I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

An envelope constructed from a single piece of material and including spaced sections constituting the front and rear walls,

and an intermediate section comprising elongated strips projecting from the end sections and having their adjacent endsconnected together, the strips of one intermediate section being adapted to be folded upon the strips of the other intermediate section, when said sections are arranged to form the envelope, side flaps projecting from one of the end sections, said end sectionconstituting the front wall having a plurality of spaced openings, adapted to receive the adjacent strip when it is desired to present said strip to View, and a closure flap for said envelope.

In testimony whereof I aflix my signature.

PIERRE FORT.
